MARC recordUsing the free-drift force balance to estimate drag coefficients and ice thickness / M.G. McPhee.
| Title: | Using the free-drift force balance to estimate drag coefficients and ice thickness / M.G. McPhee. |
| Author(s): | McPhee, M. G. |
| Date: | 1990. |
| In: | CRREL Monograph. (1990.), Vol. 90-1 (1990) |
| Abstract: | Steady-state, "free-drift" momentum equation is used to show that measurements of wind velocity, ice velocity with respect to surface geostrophic flow, mean ice mass per unit area, and angle of turning in oceanic boundary layer are enough for credible estimates of wind and water drag coefficients, provided drift periods with low internal ice-stress gradients can be identified. Alternatively, if one or other of drag coefficients is known, equations provide estimate of mean ice mass per unit area over region for which local force balance holds. |
